ABSTRACT:
A method for measuring the actual tension in an elastic string such as in a strung racquet. The method comprises holding one length of string (42) substantially a constant length, and measuring the force (58) required to maintain this length, while the tension in an adjacent section of string (36) is reduced to zero. Once the tension in the adjacent section of string has been reduced to zero, the force maintaining the first section of string a constant length is an indication of the actual string tension.
